AIOS Windows Update: Not Just "Startup Fix", But a Full Cross-CLI Reliability Chain

This update is directly tied to AIOS core architecture, not a generic Windows tip post.

Quick Answer

AIOS has three connected layers:

  1. Bridge layer: contextdb-shell-bridge.mjs decides wrap vs passthrough
  2. Session layer: ctx-agent injects/reuses ContextDB session context
  3. Execution layer: your native CLI (codex / claude / gemini) runs as usual

The Windows cmd-backed launcher fix landed in layer 1, but it protects the whole chain.

Why This Is Specifically About AIOS

Without AIOS, a .cmd startup issue is mostly a CLI boot issue.

With AIOS, that same issue breaks:

  • context continuity (session -> context:pack -> inject)
  • wrapper policy behavior (repo-only / opt-in / all)
  • downstream orchestrated flows that assume stable agent entry

So this is not an isolated shell tweak. It preserves AIOS's cross-CLI workflow contract.

What Changed

In the shared process launcher + contextdb-shell-bridge path, cmd-backed launch handling on Windows is now safer:

  • npm/cmd launcher resolution is more robust
  • unresolved wrapper entrypoints fall back with safer shell behavior
  • native executables are still preferred when available

Coverage includes Codex, Claude, and Gemini wrapper startup paths.

Reproduce in 60 Seconds

Pull latest main, restart terminal, then run:

codex

Then validate bridge routing diagnostics:

export CTXDB_DEBUG=1
codex

Expected outcome:

  • startup no longer fails on cmd-wrapper edge cases
  • bridge can still decide wrap/passthrough correctly
  • context-aware workflow remains usable without changing your daily command

End-to-End Value (AIOS View)

This fix protects the chain:

shell wrapper -> contextdb-shell-bridge -> ctx-agent -> contextdb -> native CLI

If one link breaks on Windows, your "cross-CLI with memory" promise breaks. This update hardens that link.

FAQ

Do I need to change commands?

No. Keep using codex, claude, gemini as before.

Is this only about shell startup?

No. It is a startup-layer fix with workflow-level impact in AIOS because wrapping and session context depend on that entry path.

Does this change token usage?

No direct model policy change. This update targets process reliability and wrapper behavior.
